For now I prefer Prop Firms because there are rules that must be obeyed such as maximum drawdown. This encourages me to be more disciplined in managing risk.

While trading with a broker is indeed freer. But often we do not respect the stop loss that we made ourselves.

They offer funded accounts for Forex, CFDs (MT4, MT5, cTrader) and Futures with some platforms such as Ninjatrader.

Plus, payouts can be made directly in crypto—no annoying "Rise" verification like other firms.

The owner is also behind Tickmill , a reputable broker, so they’re pretty legit.
